<script>
function checkname()
{


    /*if(!isNaN(name))
    {
        alert('Enter characters only');
        document.reg.Name.value='';
        document.reg.Name.focus();
    }
    */
        name=document.reg.Name.value;

    var letters = /^[A-Za-z]+$/;
   if(name.match(letters))
     {
      return true;
     }
   else
     {
     alert("No numbers or blank space please");
    document.reg.Name.value='';
        document.reg.Name.focus();
     return false;
     }
}
